No reason that I can think of. Yes it's possible, but I've never heard of such an implementation. If you are visualizing something like:
class set : public list
{
};This says that a set is-a list, which it can't be because a set does not do everything that a list does. Perhaps you wanted a has-a construct where the set contains a list.

Lets forget sets and concentrate why linked lists would intersect and why/when would someone do this.

If It's difficult to explain here, you can direct me to a link or something on that. ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Hi everyone!
I'm using CDatabase & CRecordSet (ODBC in MFC) and I wonder how can I save the content of an RichEdit control as a record (or better to say: a field) in MS-Access database (*.mdb).
Thank you masters!

You probably want a field that's a BLOB type (I guess Access would call that Attachment type?), then you can just store the raw bytes of the CRichEdit control (accessed via the CRichEditCtrl::StreamIn[^] and CRichEditCtrl::StreamOut[^] methods) in that field, specifying some of your code in the pfnCallback field of the EDITSTREAM[^] structure you pass to the method.
Of course, you could just store the text (as opposed to the rich text, but accessed via the same methods) in a sufficiently large Text field.

Access has a OLE Object field type. That is used to hold large, binary data.

Import Word's type library into your project. This will add a bunch of Word-related classes to your project. Then you can start with something like:
_Application app;
if (app.CreateDispatch("Word.Application") == TRUE)
{
Documents docs = app.GetDocuments();
_Document doc = docs.Open(COleVariant("thesis.doc"), vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional);
docs.Close();
app.Quit();
}

I am writing an application using C++ and MFC. A few weeks ago, I wrote the following
line of code:
<br />
IMPLEMENT_SERIAL( CMainWindow, CFrameWnd, 1 )<br />
The code worked. The class CMainWindow has only one constructor and that constructor does not take any arguments. Today, I changed that constructor to take a single argument, a reference to an
fstream object. Now, I get the following error messages from the compiler on the line shown above.
There error messages are:
<br />
error C2512: 'CMainWindow' : no appropriate default constructor available<br />
error C2758: 'CMainWindow::debugFile' : must be initialized in constructor base/member initializer list<br />
Note that debugFile is the name of the formal parameters for the constructor CMainWindow. I would
really like to be able to serialize the class CMainWindow and at the same time, I would like the class constructor to take one argument. What should I do?
Thanks
Bob

You should follow the 'suggestions' of the two errors, in order to make your class serializable again.
For instance, the documentation [^] states
Defining a Constructor with No Arguments
MFC requires a default constructor when it re-creates your objects as they are deserialized (loaded from disk). The deserialization process will fill in all member variables with the values required to re-create the object.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

CPallini wrote a very nice version of "Tough".
The serialisation mechanism is very good for simple objects, but I've found it to be very fragile when you want to do any real work. I know others here disagree with me on this though!

Thanks for the responses. It seems to me that the MFC serialization approach is less then ideal. I solved the problem by making the argument to the constructor optional. This is also less than ideal it gets the job done.

i have a question of how to creat a poolObject
this is the code :
template<class t="">
class objectPool : public GenericObjectPool
{
static objectPool<t> *thePool;
static void createPool()
{
thePool = new objectPool<t>();
//here we need to create the pool itself ...
//or in the c'tor of the parent ..
//the register could happen in the c'tor of the parent
//but we either do it here
....
}
}
can someone help me ?

Sorry - where does GenericObjectPool come from? It's not from MFC, that's for sure...
|
|
|
|

I think its better to user a Singlton class if you need only one Object pool and create the Pool in its constructor.
If you need multiple object pool use a Class Factory. any way you can create pool in its constructor.
What is the GenericObjectPool, and what it does?

Hai,
Please tell me how can i obtain the list of hardware installed in a particular system using Win32 API using VC++. I know that all the information about the system such as memory management, file management are present in WIN32API. But i am not able to obtain those info. I visited msdn. But i just need an idea of how to program using the available info.
|
|
|
|
|
SetupAPI provides methods for getting hardware details. Have a look at that.
|
|
|
|
|
Thank You..I looked at it..But i am doing a project on obtaining these info from system using C functions and Win32 API functions. I need the functions so that i can proceed with my work. I am a novice in this area.

You could obtain information from the registry such as that under HKEY_LOCAL_MACHINE/System/Enum/, though it may be hard work to do so depending on how much information you want. Though be careful not change anything in the registry!
